Idk what ingredient in this serum irritated my skin but it did not work out for me. However, for my mom, my best friend and even my friends’s mom it worked wonders on them. It faded their dark marks but for me it just irritated my skin. So far the other products that my skin hated are the cosrx bha power liquid, I’m from mugwort essence, Tiam vita b3 and hada labo blue bottle lotion/toner. I’m not sure what ingredient they have in common or what but this serum which everyone loves just didn’t work on my skin.
I repurchased several bottles for me and my sister for the dark spots that appear after acne. It helps lighten the dark spots faster. I need to see if this comes in a bigger bottle.
It's super gentle and quite small but with consistent use, this ampoule works great to soothe small spots and overall redness while brightening the skin!
I bought this serum cause I heard lot of good things about the old formula and I can't find that old version anymore, so hopefully this new version work great as the old one.
